Is it possible to install ClockworkMOD Recovery on a Sony Ericsson W8 with Android 2.1? ROM Manager is asking for the phone model, and W8 is not listed nor any Xperia phone. Is there a different version for my device?
According to directions on this site, there is a non-official (and therefore unsupported) version of Clockworkmod Recovery for the W8 available here. It doesn't provide instructions on installing it, but I imagine you do it with either fastboot, or ODIN/Heimdal.
Alternatively, use xRecovery as described in these instructions. It's very similar to CMR, but according to the site you will need ROMs packaged specifically for this recovery:
